There are two 16th-century French jurists of this name. The older of the two is the author of De auctoritate sacri magni consilii (TUI 1584, t. 16) and De bigamia (TUI 1584, t. 9). J. studied law at Toulouse and taught there briefly. He may also have taught at Bourges around 1507–8. He served as councillor to the archbishops of Albi from 1510 to 1516. The De auctoritate is notable for its attempt to balance the power of the Grand Conseil with that of the parlements. The additiones to this work of Nicolas Bohier are more favorable to the authority of the Grand Conseil. We are unsure whether the Tractatus de parlamentis, et collatione parlamentorum, which appears as a separate treatise in TUI 1584, t. 16, also with additiones of Bohier, is a separate work or part of the original De auctoritate sacri magni consilii. We rather suspect that the latter is the case.
